METHODS FOR HEALTH CARE
LEADERS WITH WELL DESIGND
QUESTIONS AND CORRECT ANSWERS
Sensory Exploration - Answer involves activities that engage the senses—touch,
sight, hearing, smell, and taste—helping children explore and understand the world
around them
autonomy versus shame/doubt stage - Answer This stage involves a child's journey
toward independence and decision-making
trust versus mistrust stage - Answer Infants learn to rely on caregivers for their
basic needs, fostering trust—while inconsistency in meeting these needs can lead
to mistrust, suspicion, and anxiety about their environment.
object permanence - Answer the understanding that something still exists even
though it cannot be seen or heard
sensorimotor stage - Answer Infants (0-2 years old) explore through senses and
actions, developing an understanding of object permanence and laying cognitive
foundations
cross-sectional study - Answer A study that analyzes data from a population at a
single point in time to assess health outcomes or service utilization.
, Randomized control trial - Answer An experimental study design where
participants are randomly assigned to treatment or control groups to evaluate
intervention effectiveness.
time series - Answer A method that examines data points collected or recorded at
regular time intervals to identify trends or impacts over time.
pre test- post test - Answer A design that compares outcomes before and after an
intervention to assess its impact within the same population.
Clinical trial - Answer A research study that tests new medical strategies,
treatments, or devices in human participants under controlled conditions.
Meta analysis - Answer A statistical technique that combines results from multiple
studies to determine overall trends or effects.
Literature Review - Answer A comprehensive summary of existing research on a
specific topic to identify patterns, gaps, or consensus.
Case study - Answer An in-depth, contextual analysis of a single case or a small
group to explore complex healthcare issues or systems.
Cohort Study - Answer A longitudinal study where a group of individuals is
followed over time to observe health outcomes related to exposures.
Person product-moment correlation coefficient - Answer A measure of the strength
and direction of a linear relationship between two continuous variables.
,Regression analysis t-test - Answer A statistical method to assess relationships
between variables and test if regression coefficients differ significantly from zero.
Analysis of Varience - Answer A statistical technique (ANOVA) used to compare
means across multiple groups to see if at least one differs significantly.
Wilcoxon signed rank tests - Answer A non-parametric test used to compare two
related samples when data isn't normally distributed.
Bayesian approach - Answer A statistical method that updates the probability for a
hypothesis as more evidence becomes available.
Mann-Whitney test - Answer A non-parametric test used to determine if there is a
difference between two independent groups.
Analysis plan - Answer A structured outline detailing how data will be collected,
analyzed, and interpreted in a research study.
Study population - Answer The specific group of individuals selected for a
research study, defined by inclusion and exclusion criteria.
Data Collection - Answer The process of gathering information relevant to a
research question using methods like surveys, interviews, or records.
Research design - Answer The framework or blueprint for conducting the
research, including methods for data collection and analysis.
, Patient attrition - Answer The loss of participants during a study, which can impact
the validity of results and generalizability.
descriptive statistics - Answer Statistical methods used to summarize or describe
features of a dataset (e.g., mean, median, standard deviation).
Chi square test - Answer A test to examine associations between categorical
variables by comparing observed and expected frequencies.
Factor analysis - Answer A method used to identify underlying variables (factors)
that explain patterns in a set of observed variables.
Interferential statistic - Answer Statistical methods that use sample data to make
generalizations or predictions about a population.
Reimbursement records - Answer Data documenting payments made to providers
for services, useful for cost analysis and utilization tracking.
CMS - Answer Centers for Medicare & Medicaid Services, the federal agency
overseeing major healthcare programs and reimbursement rules.
LOS - Answer Length of stay; the number of days a patient spends in a healthcare
facility, used as a measure of efficiency or resource use.
Claims records - Answer Administrative data submitted by providers for
reimbursement, used to analyze service utilization and billing trends.
